The UC2823ADW is a type of pulse width modulated(PWM) DC-DC switching controller designed and provided by Texas Instruments. It is used as a voltage regulator and it is also a DC-DC switching controller. It is usually used in high voltage switching applications such as automotive and industrial applications, and when used in these applications it has the ability to offer efficient power delivery and reliable protection of upstream sources. This DC-DC switching controller has high output voltage accuracy, fast response time and protection against load short circuits, over-current and over-temperature conditions.

The UC2823ADW uses a closed loop system with a feedback network from the output voltage to the voltage regulator. The output voltage set point is regulated through the pulse width modulation of the switching controller, which works by generating modulating levels for the switching of the switches in the control circuit. This operating principle of the UC2823ADW enables it to accurately regulate the output voltage from the traditional power sources that it is connected to. This feature makes it an ideal solution for use in a wide range of applications.

The UC2823ADW has good EMI performance and it is capable of providing low on-state resistance. It also features low starting, no load current and high efficiency, along with a low audible noise operation. This DC-DC switching controller is also designed to offer a wide range of protection measures, such as short-circuit, over-current and over-temperature protection. Its high-frequency operation also ensures a fast response time when switching and making it an ideal choice for demanding automotive and industrial applications.

The UC2823ADW offers a wide input voltage range of 4.5V to 40V, a wide output voltage range of 3.3V to 40V, and a maximum output current of 4.5A. In addition, it features an operating temperature range of -40°C to 85°C and a switching frequency of 400kHz to 2.2 MHz. It also has an adjustable soft-start time and fast transient response. This DC-DC switching controller is available in a 14-pin SOIC surface mount package and is designed to be used in applications such as automotive, industrial, and other open-loop voltage regulation applications.
